Delphi中的外部异常EEFFACE [英] External Exception EEFFACE in Delphi
问题描述
在使用Delphi 2009调试应用程序时，有时会发生以下异常：
While debugging my application with Delphi 2009, I sometimes get the following exception occurring:
（来源： beholdgenealogy.com ）
这仅偶尔发生，但是按OK后，我的IDE和程序都可能冻结。如果幸运的话，我有时可以在Delphi中执行File / SaveAll，但有时却不能。无论哪种方式，我都会陷入困境，然后我唯一能做的就是使用Windows Task Manager关闭Delphi。当然，如果我无法保存SaveAll，那么我将丢失自上次保存以来所做的所有编辑。
This only happens occasionally, but after pressing OK, then my IDE and program both may freeze. If I am lucky I can sometimes do a File/SaveAll in Delp but sometimes I can't. Either way I am stuck and then the only thing I can do is use Windows Task Manager to shut down Delphi. Of course, if I was unable to SaveAll, then I lose all the edits I had made since last saving.
我已经安装了所有的Delphi 2009 Update，直到包括Update4。我还安装了IDE Fix Pack 2009 2.9。
I have all the Delphi 2009 Updates installed right up to and including Update 4. I also have IDE Fix Pack 2009 2.9 installed.
EurekaLog为我捕获了错误，并且错误报告给出了以下调用堆栈：
The Error is trapped for me by EurekaLog, and the error report gives the following call stack:

如您所见，所有调用堆栈在Delphi和Windows中。它根本不会连接到程序中的任何行。
As you can see, all of the call stack is in Delphi and Windows. It does not connect back at all to any line in my program.
我看了看网页：外部异常EEFFACE 并将其从德语翻译为英语，但这似乎是在谈论Delphi C ++，而我没有完全不使用C ++。
I have looked at the webpage: External Exception EEFFACE and translated it from German to English, but it appears to be talking about Delphi C++ whereas I don't use C++ at all.
我的问题是我不知道是什么原因导致的，因为它并没有始终如一地发生。我什至不知道在哪里可以找到它或如何找到它。
My problem is I have no idea what might be causing this as it does not happen consistently. I have no idea even where to look to find it or how to track it down.
有人知道这是什么以及如何找到或至少防止它吗？
Does someone know what this is and how I can track it down or at least prevent it from happening?
Alex of EurekaLog发布了此内容以回应我在论坛上的查询：
Alex of EurekaLog posted this in response to my query on their forum:
我认为这可能是Delphi的
调试器中的错误。可能与
评估工具提示或类似的
相关。
I think it may be a bug in Delphi's debugger. Possibly related to evaluation tooltips or something similar.
亲自体验一下-系统模块中有C ++
异常（EEFFACE是
a VCL例外的特殊代码。当
VCL遇到未知的C ++
例外-将其包装到
EExternalException对象中，代码=
EEFFACE），并且调用堆栈包括
Delphi调试器的单位：
See for yourself - we have an C++ exception in system module (EEFFACE is a special code for VCL exception. When VCL encounters an unknown C++ exception - it wraps it into EExternalException object with code = EEFFACE) and call stack includes Delphi debugger's units:

我认为您应该将此
描述发布到Embarcadero的质量
Central。
I think that you should post this description to Embarcadero's Quality Central.
尝试禁用 IDE集成
复选框（位于IDE的
EurekaLog /中EurekaLog IDE选项
菜单）并运行您的应用程序-如果行为发生变化，请参阅
。
Try to disable "IDE integration" check-box (it's located in IDE's "EurekaLog"/"EurekaLog IDE Options" menu) and run your application - see if there will be a change in behavior.

我现在已向Quality Central提交了一份报告，网址为：
I have now submitted a report to Quality Central at:
http://qc.embarcadero.com/wc/qcmain.aspx?d=81881
希望有了这些信息，Embarcadero将能够在以后的版本中防止这种情况。
Hopefully with this information, Embarcadero will be able to prevent this in future releases.
4年后，我回到这个问题，并意识到几个月前，我找到了解决方案，所以我将其发布在这里，以供其他可能遇到此问题的人使用。
I come back to this question over 4 years later, and realize that a few months ago, I found the solution, so I am posting it here for anyone else who may encounter this.
问题与解决方法在 Olaf Monien 的博客中提供，该内容来自2009/07/22，标题为Delphi 2009 / Windows 7 / 64位调试器崩溃的解决方法。
The problem and solution were provided in Olaf Monien's blog, in a post from 2009/07/22 titled Delphi 2009 / Windows 7 / 64 bit Debugger Crash Workaround.
奥拉夫（Olaf）在该帖子上的说明对我来说非常有效，问题已经解决了。我感谢他在博客文章中的评论。
Olaf's instructions on that post worked perfectly for me, and the problem is gone. I thanked him in a comment on his blog post.
正如@rossmcm在他的评论中指出的那样，Olaf的博客文章不再存在，而是该帖子仍可以在Internet存档上找到。相反，请查看克里斯·米勒（Chris Miller）有关该问题的信息（现在也只能在Internet档案中获得），其中包含指向现在在Embarcadero拥有永久性住所的修补工具。
As @rossmcm points out in his comment, Olaf's blog post is no longer there, but the post can still be found on the Internet Archive. Instead, check out Chris Miller's information about the problem (now also only available on the Internet Archive) which includes a link to the patch tool that now has a permanent home at Embarcadero.
推荐答案
这显然是Delphi评估程序（属于编译器的一部分）中发生的事情。奇怪的是，如果实际上是通过writeobj.c进行的，则肯定不是很正确。如果您可以通过测试用例来重现此内容，请在QualityCentral（ http://qc.embarcadero.com
This is clearly something happening in the Delphi evaluator (which is part of the compiler). The odd thing is that if it is, in fact, going through writeobj.c, something is certainly not quite right. If you can reproduce this with a test case, please report it in QualityCentral (http://qc.embarcadero.com).
EEFFACE是C ++使用的SEH异常代码，它泄漏了某些Delphi代码（在本例中为IDE本身）。当异常代码不是Delphi生成的异常或与硬件相关的异常时，Delphi只需将其映射到EExternalException。
EEFFACE is the SEH exception code used by C++, which is "leaking" out to some Delphi code (in this case the IDE itself). When the exception code is not a Delphi generated exception or a hardware related exception, Delphi simply maps it to EExternalException.
这篇关于Delphi中的外部异常EEFFACE的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
